Multiple Routes to Oestrogen Antagonism
Several lines of evidence attest to the existence of alternative ligand binding sites on the oestrogen receptor (ER), including non-competitive inhibition by trilostane or tamoxifen. It is possible that the inhibitory action of conventional oestrogen agonists at high concentrations may indicate that they too interact at alternative ER sites, albeit at low affinity. To test this possibility an o...
متن کاملMultiple Routes to Perceptual Learning
A listener’s ability to utilize indexical information in the speech signal can enhance their performance on a variety of speech perception tasks. It is unclear, however, whether such information plays a similar role for spectrally reduced speech signals, such as those experienced by individuals with cochlear implants. The present study compared the effects of training on linguistic versus index...
متن کاملStructural aspects of agonism and antagonism in the oestrogen receptor.
We have determined the three-dimensional structures of both alpha- and beta-forms of the ligand-binding domain of the oestrogen receptor (ER) in complexes with a range of receptor agonists and antagonists. Here, we summarize how these structures provide both an understanding of the ER's distinctive pharmacophore and a rationale for its ability to bind a diverse range of chemically distinct comp...
متن کاملComputing Multiple Watchman Routes
We present heuristics to compute multiple watchmen routes. Given a polygon (with or without holes) and a parameter k, we compute a set of k routes inside the polygon such that any point inside the polygon is visible from at least one point along one route. We measure the quality of our solutions by either the length of the longest route and the sum of route lengths, where the goal is to minimiz...
متن کاملMultiple routes to reduced interspecific territorial fighting in Hetaerina damselflies
Interspecific territoriality may be adaptive if territories contain depletable resources that are valuable to both species, but it can also arise as a maladaptive by-product of intraspecific territoriality. In the latter scenario, sympatric species ought to diverge in ways that reduce interspecific fighting. We studied 4 Hetaerina damselfly species that can be found in sympatry in North America...
